This commit adds a pair of scripts that run the memory model on litmus tests, checking that the verification result of each litmus test matches the result flagged in the litmus test itself. These scripts permit easier checking of changes to the memory model against preconceived notions. To run the scripts, go to the tools/memory-model directory and type "scripts/checkalllitmus.sh". If all is well, the last line printed will be "All litmus tests verified as was expected." Signed-off-by: Paul E.

# Run herd tests on all .litmus files in the specified directory (which
|
|
# defaults to litmus-tests) and check each file's result against a "Result:"
|
|
# comment within that litmus test. If the verification result does not
|
|
# match that specified in the litmus test, this script prints an error
|
|
# message prefixed with "^^^". It also outputs verification results to
|
|
# a file whose name is that of the specified litmus test, but with ".out"
|
|
# appended.
|
|
#
|
|
# Usage:
|
|
# sh checkalllitmus.sh [ directory ]
|
|
#
|
|
# The LINUX_HERD_OPTIONS environment variable may be used to specify
|
|
# arguments to herd, whose default is defined by the checklitmus.sh script.
|
|
# Thus, one would normally run this in the directory containing the memory
|
|
# model, specifying the pathname of the litmus test to check.
|
|
#
|
|
# This script makes no attempt to run the litmus tests concurrently.
